Question

75-(5х+х) умножить на 3=39

Answer 1

75-(5х+х)*3=39

75-18х=39

-18х=39-75

-18х=-36

х=-36:(-18)

х=2 

Answer 2

75-(5х+х)·3 = 39;
75-18х = 39;
-18х = -36;
х = 2.

Answer 3

To solve the equation (75 - (5x + x)) * 3 = 39, let's break it down step by step:

First, simplify the expression within the parentheses: 75 - (5x + x) becomes 75 - 6x.

Now we have the equation (75 - 6x) * 3 = 39.

Next, apply the multiplication: 3 * (75 - 6x) = 39.

Distribute the 3 to both terms inside the parentheses: 225 - 18x = 39.

Now, isolate the term with x by moving the constant term to the other side of the equation: 225 - 39 = 18x.

Simplifying the left side: 186 = 18x.

Finally, solve for x by dividing both sides of the equation by 18: x = 186 / 18.

Calculating the value: x = 10.333...

So, the solution to the equation (75 - (5x + x)) * 3 = 39 is approximately x = 10.333.
